The fire left the apartments’ two residents without a dwelling and killed their cat. Red Cross workers had located temporary quarters for one of the occupants, said the deputy chief.

It didn’t take long to find the cause: One of the tenants said a bed covering had ignited after it had come too close to an electric heater. “He tried to extinguish before calling 911,” said Deputy Chief Dong.

The preliminary estimate of damage to the apartment building was placed at $100,000, while the loss to contents hadn’t been finalized by Tuesday afternoon.

Firefighters returned to their station at 7:25 a.m., only to be summoned to another blaze four minutes later on Ashby Avenue at Martin Luther King Jr. Way.

“On arrival, they found smoke coming from the side of a two-story duplex,” said the deputy chief.

Moments later, the heat blew out a side window and flames into the open air, scorching the side of the neighboring duplex and triggering a second alarm.

“We had 27 firefighters, five engines, two trucks, two paramedic units and three chief officers” fighting the blaze, he said.

Electrical power to the immediate area was also cut during the blaze to protect the emergency crews, and one of the five occupants displace by the blaze was also evaluated for additional medical care.

The cause of the blaze remained under investigation Tuesday afternoon, but damage to the structure was set at $150,000, with damage to contents still to be determined.

While the dire damage was largely confined to the first floor unit, the contents of the second story apartment sustained extensive smoke damage, said Deputy Chief Dong.

In addition, the exterior of the nearby duplex suffered from paint damage.

The fire also forced the closure of MLK at one of Berkeley’s busier intersections, and the road remained closed at noon while investigators remained on scene seeking to learn the cause of the fire.

Five residents of the duplex were displaced by the fire, including one toddler.

Firefighters afield

Two Berkeley firefighters were waiting in Houston Tuesday morning to see if they’ll be needed in the emergency spawned by Hurricane Gustav.

Deputy Chief Dong said they had been dispatched to Lafayette, La., with the Oakland Fire Department’s Search and Rescue Team but learned they weren’t needed, and then headed back to Houston to wait in case they are needed elsewhere.

BART blaze

Berkeley firefighters also handled a small Aug. 26 blaze that temporarily halted traffic on the BART near its North Berkeley Station.

The call came at 6:46 p.m., resulting in the dispatch of a single engine to the tracks at Curtis and Gilman streets.

On arrival, the firefighters saw smoke coming from the overhead tracks and called a first alarm. When the truck arrived, firefighters extended the ladder and climbed up to the tracks, while BART police shut down power to the third rail that powers the trains.

A quick investigation determined that a fiberglass covering had fallen onto the third rail, which packs of punch of 1000 volts of DC power.

After killing the flames with a dry chemical extinguisher power was restored to the system and the trains rolled again after an hour’s delay.
